i asked my local store for Ferric Oxide and was asked What is that. I turned and ordered some from BRS put it in a bag and added it to my Magnum 350 canister for right now. Cleared up my Cyno Algae in a matter of days. Will order a reactor and do it the proper way in a few weeks

I use this in a BRS dual reactor and it works to keep phosphates down around 0.00 ppb in my system. When phosphates climb to 0.06 ppb on my Hanna Checker I change the GFO and they are back to 0.00 ppb within 48 hours. I have never had an algae outbreak (actually I've never had ANY algae) while using this GFO to keep phosphates in check.
